find the string in the std::list

[itkid]

Hi, I am storing all the barcode into below declared list typedef std::list<char* > SERIAL_NUM_BARCODE_LIST; SERIAL_NUM_BARCODE_LIST SerialNumDescList; Now before adding to list I have to check whether barcode exist in the list or not. If barcode does not exist than only I have to add it. typedef std::list<char* >::iterator BARCODE_LIST_ITER; BARCODE_LIST_ITER BarcodeListIter; for(BarcodeListIter = SerialNumBarcodeList.begin(); BarcodeListIter != SerialNumBarcodeList.end();BarcodeListIter++) strcmp(SerialNumBarcodeList.front(),Barcode) Is there simple find method present in STL to check inside the list. Thanks:-D

You can simply compare the contents of the iterator (so, the string) with the name of the new barcode. To access the string through the iterator, just use this: (*BarcodeListIter)

Ideally, you should store the barcodes as strings instead of a pointer. For example:

std::liststd::string SerialNumBarcodeList;
...
std::list<string>::const_iterator it = std::find(SerialNumBarcodeList.begin(), SerialNumBarcodeList.end(), BarCode);
if (it != SerialNumBarcodeList.end())
{
// Found!
...
}

Thank dear, I hope it will take care the boundary condition where it is checking the barcode with SerialNumBarcodeList.end() :)
